摘要:
射孔在非常规油气藏的开发中,作为压裂的前导工艺,为后续油气采集提供通道??⒁恢志哂斜浔诤褡痘〗峁挂┬驼值男滦头浅9嬗推馗吡鞫噬淇椎?数值仿真显示,新型射孔弹形成的射流头部初速度更高、形态更稳定。模拟地层条件的流动效率和现场应用试验表明,与深穿透射孔弹相比,新型射孔弹形成的孔道具有更高的流动效率,摩阻更小,在非常规油气藏的开发上颇具优势。
Abstract:
In the development of unconventional oil and gas reservoirs, perforation is first used as a leading process for fracturing, followed by a channel for oil and gas in subsequent production. In this paper, a new type of perforating charge with a variable wall thickness liner is developed, which has high flow efficiency and is suitable for fracturing of unconventional oil and gas reservoirs. Numerical simulation shows that the jet head formed by the new perforating charge has higher initial velocity and more stable shape. The flow efficiency of simulated formation conditions and field application tests show that the new perforation charge has a higher flow efficiency and a smaller friction than the deep penetration charge, which makes the new perforating charge have advantages in the development of unconventional oil and gas reservoirs.
